종래의 간냉 및 직냉 겸용 냉장고는 한국공개특허 제2003-0057790호에 제시된 것이 있다.Conventional intercooling and direct-cooling combined refrigerators are those disclosed in Korea Patent Publication No. 2003-0057790.

상부가 개구되게 형성된 본체(100)의 내부에 김치가 저장되는 저장실이 형성되고, 본체(100)의 상부 개구부에는 상기 저장실을 개폐하는 뚜껑이 힌지 결합된다.A storage chamber in which kimchi is stored is formed in the interior of the main body 100 formed to have an upper opening, and a lid for opening and closing the storage chamber is hinged to the upper opening of the main body 100.

그리고, 상기 저장실의 하측에는 김치 냉장고를 제어하는 콘트롤부와 냉동사이클의 구성요소인 응축기(미도시)와 압축기 등이 설치되는 기기실이 마련되고, 저장실의 내측벽의 둘레에는 냉매관으로 구성된 증발기가 설치되어 저장실의 내부를 저온상태로 유지할 수 있게 된다.In addition, a control unit for controlling the kimchi refrigerator, a condenser (not shown), a compressor, and the like, which are components of a refrigeration cycle, are installed at a lower side of the storage compartment, and an evaporator configured as a refrigerant tube is formed around the inner wall of the storage compartment. It is installed to keep the inside of the storage room at a low temperature.

그리고, 저장실의 내측벽의 하측 둘레에는 저장실에 저장되는 김치를 숙성시키기 위하여, 열선으로 구성된 숙성히터가 설치된다.And, in order to ripen the kimchi stored in the storage chamber, a aging heater composed of hot wires is installed around the lower side of the inner wall of the storage chamber.

또한, 상기 저장실의 전면 및 후면 내측벽에는 고내로 외기를 냉각하여 유입시키기 위해 상호 연설된 덕트가 높이방향으로 형성되고, 덕트의 일측벽에는 냉매가 그 내부로 흐르는 냉매관이 가로방향을 따라 반복적으로 설치된다.In addition, the front and rear inner walls of the storage chamber are formed with mutually ducts extending in a height direction for cooling and introducing outside air into the air, and one side wall of the duct repeatedly has a refrigerant pipe in which a refrigerant flows therein. Is installed.

한편, 상기 덕트의 관로상에는 냉각팬이 장착되는 바, 그 냉각팬은 외기를 흡입하여 덕트를 통해 유입시키고, 그 냉매관에 의해 냉각된 냉기를 고내로 유입시킨다.On the other hand, the cooling fan is mounted on the duct pipe, the cooling fan sucks the outside air and flows through the duct, and the cold air cooled by the refrigerant pipe flows into the inside of the chamber.

또한, 상기 덕트의 고내측 측벽에는 상기 냉각팬에 의해 유입되어 냉각된 냉기를 고내측으로 유입시키기 위한 다수의 유입공이 형성된다.In addition, a plurality of inflow holes are formed on the inner sidewall of the duct to introduce the cooled cool air introduced by the cooling fan to the inner side of the duct.

바람직하게, 상기 콘트롤부와 연결되며, 저장고의 둘레에 설치된 냉매관과, 상기 덕트의 내측벽에 설치된 냉매관은 솔레노이드 밸브로부터 분기되어 장착되는 바, 그 솔레노이드 밸브는 선택적으로 냉매를 각 냉매관을 통해 유출시킨다.Preferably, the refrigerant pipe is connected to the control unit, and the refrigerant pipe installed around the reservoir and the refrigerant pipe installed on the inner wall of the duct are branched from the solenoid valve, and the solenoid valve selectively connects the refrigerant to each refrigerant pipe. Spill through.

그와 동시에, 상기 냉각팬을 동작시켜 덕트에서 냉각된 냉기를 상기 유입공을 매개로 저장고내로 유입시켜 급속 냉각이 이루어질 수 있도록 한다.At the same time, the cooling fan is operated so that cold air cooled in the duct is introduced into the reservoir through the inlet hole so that rapid cooling can be achieved.

도 1을 참조하면, 각각의 저장고(R1, R2, R3, R4)는 각각 직접 냉각수단과 간접 냉각수단이 동시적으로 적용되는바, 그 저장고(R1, R2, R3, R4)의 내측벽 둘레에는 주 냉매관이 내설되며, 그 주 냉매관의 후면에는 덕트가 형성된다.Referring to Figure 1, each of the reservoirs (R1, R2, R3, R4) is applied to the direct cooling means and indirect cooling means at the same time, each around the inner wall of the reservoir (R1, R2, R3, R4) The main refrigerant pipe is built in, and a duct is formed on the rear surface of the main refrigerant pipe.

또한, 그 덕트에는 보조 냉매관(22a, 22b, 22c, 22d)이 내설되고, 덕트의 내부 소정위치에는 각각 냉각팬(24a, 24b, 24c, 24d)이 장착되어 외부 냉기를 저장고(R1, R2, R3, R4)내로 유입시킨다.In addition, auxiliary coolant pipes 22a, 22b, 22c, and 22d are installed in the duct, and cooling fans 24a, 24b, 24c, and 24d are mounted at predetermined positions of the duct, respectively, to store external cold air (R1, R2). , R3, R4).

먼저, 본 발명에 따른 다수의 직냉 및 간냉 겸용 분리실이 구비된 김치냉장고(100)가 기설정온도로 평상 운전시에는 주냉각장치 즉, 주 냉매관을 통한 냉각을 행한다.First, the kimchi refrigerator 100 equipped with a plurality of direct cooling and intercooling separation chambers according to the present invention performs cooling through a main cooling device, that is, a main refrigerant pipe during normal operation at a preset temperature.

이때, 사용자가 다수의 저장고(R1,R2, R3, R4) 중 특정 저장고를 선택하고, 그 저장고의 온도를 설정하면, 상기 제어부는 해당 설정온도가 보조 냉각(즉, 보조 냉매관(22a, 22b, 22c, 22d)을 통한 냉각)이 필요한 온도인지의 여부를 데이터 저장부에 저장된 기설정온도와 비교함으로써 판단한다.At this time, when the user selects a specific reservoir among a plurality of reservoirs R1, R2, R3, and R4, and sets the temperature of the reservoir, the controller sets the corresponding temperature to the auxiliary cooling (that is, the auxiliary refrigerant pipes 22a and 22b). , 22c, 22d) to determine whether the required temperature is compared with the preset temperature stored in the data storage unit.

만약, 보조 냉각이 필요한 경우라고 판단되면, 상기 솔레노이드 구동부에 밸브 개방 제어신호를 인가하여 해당 밸브를 개방한다.If it is determined that auxiliary cooling is required, the valve is opened by applying a valve opening control signal to the solenoid driving unit.

밸브가 개방됨과 동시에, 제어부는 상기 냉각팬 구동부에 구동 제어신호를 인가하여 해당 저장고의 냉각팬(24a)이 구동되도록 한다. 냉각팬(24a)이 구동되고 상기 솔레노이드 밸브가 개방됨으로 인해 상기 제 1 덕트(20a) 및 제 2 덕트(20b)로 유입된 외기는 냉기로 변환되고 유입공을 통과해서 해당 저장고(예컨대, R1)로 유입된다. 따라서, 해당 저장고(예컨대, R1)내의 저장물은 해당 설정온도로 급속 냉각된다.Simultaneously with the opening of the valve, the control unit applies a driving control signal to the cooling fan driving unit to drive the cooling fan 24a of the corresponding reservoir. As the cooling fan 24a is driven and the solenoid valve is opened, the outside air introduced into the first duct 20a and the second duct 20b is converted into cold air, passes through the inlet hole, and passes through the corresponding reservoir (eg, R1). Flows into. Thus, the storage in the reservoir (eg R1) is rapidly cooled to the set temperature.

그리고, 상기 제어부는 상기 다수의 저장고(R1, R2, R3, R4)중 예약 온도변경 시간이 설정된 저장고가 존재하는 지의 여부를 판단하여, 해당 저장고가 존재하고 예약 시간이 도래한 경우에는 다시 해당 설정온도가 보조 냉각이 필요한 온도인지의 여부를 판단하는 단계로 복귀한다.The controller may determine whether a reservoir having a reserved temperature change time exists among the plurality of reservoirs R1, R2, R3, and R4, and if the reservoir exists and the reservation time arrives, the corresponding setting is again set. Returning to the step of determining whether the temperature is a temperature at which auxiliary cooling is required.

그러나, 종래의 이러한 냉장고는 제상시 동시 출력으로 순간 최대 소비전력량이 상승되는 문제점이 있으며, 제상 완료 후 냉각시에도 동시 운전으로 인한 비효율이 있다.However, such a refrigerator has a problem in that the maximum power consumption is instantaneously increased by simultaneous output during defrosting, and there is an inefficiency due to simultaneous operation even when cooling after completion of defrosting.

본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 직냉식룸의 제상온과 간냉식룸의 제상온이 겹치는지 여부를 판단하는 단계와, 두개의 제상온이 겹치면 직냉식룸의 제상온 또는 간냉식룸의 제상온을 딜레이시키는 딜레이단계를 포함하여 이루어져, 제상시 동시 출력으로 순간 최대 소비전력량이 상승하는 것을 방지하고 제상 완료후 냉각시에도 동시 운전으로 인한 비효율을 방지할 수 있는 간냉 및 직냉 겸용 냉장고의 제상제어방법을 제공하는데 그 목적이 있다. The present invention has been made in order to solve the above-described problems, the step of determining whether the defrost temperature of the direct-cooling room and the defrosting temperature of the intercooled room overlap, and if the two defrosting temperatures overlap, the defrosting temperature of the direct-cooling room or the intercooling room It includes a delay step of delaying the defrost temperature, and the defrost of the combined cold and direct cooling refrigerator that can prevent the instantaneous maximum power consumption increase by simultaneous output during defrosting and prevent inefficiency due to simultaneous operation during cooling after completion of defrosting. The purpose is to provide a control method.

전술한 목적을 달성하기 위한 본 발명의 간냉 및 직냉 겸용 냉장고의 제상제어방법은, 직냉식룸의 제상온과 간냉식룸의 제상온이 겹치는지 여부를 판단하는 단계와, 두개의 제상온이 겹치면 직냉식룸의 제상온 또는 간냉식룸의 제상온을 딜레이시키는 딜레이단계를 포함하여 이루어지는 것을 특징으로 한다.Defrost control method of the combined cold and direct cooling of the present invention for achieving the above object, the step of determining whether the defrost temperature of the direct-cooling room and the defrosting temperature of the intercooled room overlap, and if the two defrosting temperature overlaps the direct cooling room It characterized in that it comprises a delay step of delaying the defrosting temperature of the defrosting temperature or intercooled room.

이 구성에 의하면, 제상시 동시 출력으로 순간 최대 소비전력량이 상승하는 것을 방지하고 제상 완료후 냉각시에도 동시 운전으로 인한 비효율을 방지할 수 있는 이점이 있다.According to this configuration, it is possible to prevent the instantaneous maximum power consumption from rising at the same time during the defrosting and to prevent the inefficiency due to the simultaneous operation during the cooling after the completion of the defrosting.

상기 딜레이단계 이전에 두개 룸의 제상온의 시작시간을 판단하는 단계를 포함하여, 먼저 시작된 제상온을 유지하고 나중에 시작된 제상온을 딜레이시킨다.Determining the start time of the defrosting temperature of the two rooms before the delay step, to maintain the first defrosting temperature and to delay the defrosting temperature started later.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

참고적으로, 이하에서 설명될 본 발명의 구성들 중 종래기술과 동일한 구성에 대해서는 전술한 종래기술을 참조하기로 하고 별도의 상세한 설명은 생략한다.For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.

간냉 및 직냉 겸용 냉장고는 종래의 발명과 같이 하나의 룸에 간냉과 직냉이 모두 가능하도록 구비될 수도 있고, 본 실시예에서와 같이 하나의 룸에 간냉 또는 직냉만 가능하도록 구비될 수 있다.The intercooling and direct cooling combined use refrigerator may be provided so as to enable both intercooling and direct cooling in one room as in the conventional invention, or may be provided so as to enable only intercooling or direct cooling in one room as in the present embodiment.

간냉식으로 냉각되는 룸은 냉장 또는 냉동고 역할을 하며, 직냉식으로 냉각되는 룸은 김치 또는 야채보관고 역할을 하도록 할 수 있다.The room cooled by intercooling may serve as a refrigerator or a freezer, and the room cooled by direct cooling may serve as a kimchi or vegetable storage.

또한, 냉장고의 냉각장치는 1 컴프레셔와, 상기 컴프레셔에 연결된 다수개의 증발기와, 각각의 증발기를 제상시키는 제상히터와 같은 제상수단이 구비된다.In addition, the refrigerator of the refrigerator includes a compressor, a plurality of evaporators connected to the compressor, and defrosting means such as a defrost heater for defrosting each evaporator.

하나의 컴프레셔로부터 다수개의 증발기로 냉매를 분배하는 것은 스텝밸브 또는 솔레노이드 밸브를 통해 이루어진다.The distribution of the refrigerant from one compressor to the plurality of evaporators is via a step valve or solenoid valve.

도 2는 본 발명의 바람직한 실시예에 따른 간냉 및 직냉 겸용 냉장고의 제상제어방법 플로우 차트이다.Figure 2 is a flow chart of a defrosting control method of a combined cooling and direct cooling in accordance with a preferred embodiment of the present invention.

도 2에 도시된 바와 같이, 본 실시예의 간냉 및 직냉 겸용 냉장고의 제상제어방법은, 직냉식룸의 제상온과 간냉식룸의 제상온이 겹치는지 여부를 판단하는 단계(S1)와, 두개의 제상온이 겹치면 직냉식룸의 제상온 또는 간냉식룸의 제상온을 딜레이시키는 딜레이단계를 포함하여 이루어진다.As shown in Figure 2, the defrosting control method of the combined cold and direct cooling of the present embodiment, the step of determining whether the defrosting temperature of the direct-cooling room and the defrosting temperature of the intercooling room (S1) and the two defrosting temperature If the overlap is made of a delay step of delaying the defrosting temperature of the direct cooling room or the defrosting temperature of the intercooling room.

상기 간냉식룸은 상기 스텝밸브 또는 솔레노이드밸브가 열리는 시간을 적산하여 제상온이 결정된다.The defrosting temperature is determined by integrating the opening time of the step valve or the solenoid valve in the intercooled room.

상기 직냉식룸은 다수개 구비될 경우 복수개의 룸이 동시에 제상이 되지 않도록 제상온 간격이 제상온/직냉식룸 개수가 되도록 한다.When the plurality of the direct-cooling room is provided so that the plurality of rooms do not defrost at the same time so that the defrosting interval is the number of defrosting / direct cooling room.

직냉식룸에서 제상온이 되는 주기와 간냉식룸에서 제상온이 되는 주기가 겹치는지 여부를 마이컴과 같은 제어부에서 판단한다.(S1)It is determined by the control unit such as a microcomputer whether the cycle of defrosting in the direct cooling room and the cycle of defrosting in the intercooling room overlap.

두개의 룸이 제상온되는 시간이 겹치면 직냉식룸의 제상온 시작시간 또는 간냉식룸의 제상온 시작시간을 딜레이시켜서 두개의 룸이 동시에 제상되는 것을 방지 한다.(S3, S3')If the two rooms have a defrosting time overlap, the defrosting start time of the direct cooling room or the defrosting start time of the intercooling room is delayed to prevent the defrosting of the two rooms at the same time (S3, S3 ').

상기와 같이 제상이 제어되면, 제상시 제상히터와 같은 제상수단의 동시 출력으로 순간 최대 소비전력량이 상승하는 것을 방지하고 제상 완료후 냉각시에도 다수개의 룸의 동시 운전으로 인한 비효율을 방지할 수 있는 이점이 있다.When the defrost is controlled as described above, it is possible to prevent the instantaneous maximum power consumption from rising at the same time by the simultaneous output of the defrost means such as the defrost heater at the time of defrosting, and to prevent the inefficiency due to the simultaneous operation of a plurality of rooms during cooling after the defrost is completed. There is an advantage.

나아가, 상기 딜레이단계(S3, S3') 시키기 이전에 제상온이 겹치는 것으로 판단되면, 두개의 룸 제상온 시작시간을 타이머 등을 통해 판단하는 단계를 포함한다.(S2)Further, if it is determined that the defrost temperature overlaps before the delay step (S3, S3 '), it comprises the step of determining the two room defrost temperature start time through a timer or the like (S2).

따라서 딜레이단계(S3, S3')에서 딜레이할 때, 제상이 먼저 시작된 룸의 제상을 유지하고 나중에 제상이 시작된 룸의 제상온을 딜레이시킨다.Therefore, when delaying in the delay step (S3, S3 '), the defrosting of the room in which the defrosting is started first and the defrosting temperature of the room in which the defrosting is started later are delayed.

또한, 상기 딜레이단계(S3, S3')는 제상온이 딜레이되지 않은 룸의 온도를 룸에 설치된 온도센서 등을 통해 감지하는 감지단계를 포함한다.In addition, the delay step (S3, S3 ') includes a sensing step of detecting the temperature of the room where the defrost temperature is not delayed through a temperature sensor installed in the room.

제상온이 딜레이되지 않은 룸(즉, 제상온이 딜레이되지 않고 유지된 룸)이 제상이 완료된 후 냉각장치에 의해 정해진 온도까지 냉각될 때까지 딜레이되는 룸의 제상온을 딜레이시킨다.(제상이 완료된 후 약 2시간)The defrost temperature is delayed in the room where the defrost temperature is not delayed (i.e., the room where the defrost temperature is maintained without delay) until the defrost is completed and then cooled to a temperature determined by the chiller. About 2 hours)

상기와 같이 감지단계를 통해 제상완료 후 냉각되는 룸이 다른 룸의 제상으로 인해 효과적으로 냉각되지 않아서 온도가 높아지는 것을 방지할 수 있다. As described above, the room to be cooled after the completion of the defrost is not effectively cooled due to the defrost of another room, thereby preventing the temperature from increasing.

전술한 바와는 다르게, 제상이 먼저 시작된 룸의 냉각온도에 상관없이 제상이 완료된 후 약 10분후(정해진 시간후)에 다른 룸의 제상이 시작되도록 할 수도 있다.Contrary to the above, the defrosting of another room may be started about 10 minutes after the defrosting is completed (after a predetermined time) regardless of the cooling temperature of the room in which the defrosting first started.

상술한 바와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해 당기술분야의 당업자는 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 또는 변형하여 실시할 수 있다.As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications or changes to the present invention without departing from the spirit and scope of the invention described in the claims below It can be modified.

이상에서 설명한 바와 같은 본 발명의 간냉 및 직냉 겸용 냉장고의 제상제어방법에 따르면, 다음과 같은 효과가 있다.According to the defrosting control method of the inter-cooling and direct cooling refrigerator of the present invention as described above, has the following effects.

직냉식룸의 제상온과 간냉식룸의 제상온이 겹치는지 여부를 판단하는 단계와, 두개의 제상온이 겹치면 직냉식룸의 제상온 또는 간냉식룸의 제상온을 딜레이시키는 딜레이단계를 포함하여 이루어져, 제상시 동시 출력으로 순간 최대 소비전력량이 상승하는 것을 방지하고 제상 완료후 냉각시에도 동시 운전으로 인한 비효율을 방지할 수 있다.Determining whether the defrosting temperature of the direct cooling room and the defrosting temperature of the intercooling room overlaps, and if the two defrosting temperatures overlap, a delay step of delaying the defrosting temperature of the direct cooling room or the intercooling room. Simultaneous output prevents the instantaneous maximum power consumption from rising and prevents inefficiency due to simultaneous operation during cooling after completion of defrosting.

상기 딜레이단계는 딜레이되지 않은 룸의 온도를 감지하는 감지단계를 포함하여, 상기 룸이 정해진 온도까지 냉각될때까지 딜레이되는 룸의 제상온을 딜레이시켜, 제상 후 냉각되는 룸이 다른 룸의 제상으로 인해 온도가 높아지는 것을 방지할 수 있다. The delay step includes a sensing step of sensing a temperature of a room that is not delayed, and delays a defrost temperature of a room to be delayed until the room is cooled to a predetermined temperature, so that a room to be cooled after defrosting is defrosted in another room. The temperature can be prevented from increasing.
